NTSB narrative
The pilot reported that he was landing the tailwheel-equipped airplane on a gravel-covered runway in a left crosswind. He stated that during touchdown he used insufficient rudder and the airplane veered to the left. He added power to correct the situation and abort the landing, but the airplane's right wing contacted trees and it pivoted to the right. The airplane continued to track right, exited the gravel runway, and came to rest at the base of an embankment. The airplane sustained substantial damage to the left wing assembly and empennage. The pilot noted that there were no preimpact mechanical anomalies with the airplane.
Probable cause
The pilot's inadequate compensation for the wind conditions during landing, which resulted in a loss of directional control and collision with trees.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2010-10-02.
